Quarterbacks are ranked according to DYAR, or Defense-adjusted Yards Above Replacement. This gives the value of the quarterback's performance compared to replacement level, adjusted for situation and opponent and then translated into yardage. DYAR (and its cousin, YAR, which isn't adjusted based on opponent) is further explained here [1].
The other statistic given is DVOA, or Defense-adjusted Value Over Average. This number represents value, per play, over an average quarterback in the same game situations. The more positive the DVOA rating, the better the player's performance. Negative DVOA represents below-average offense. DVOA (and its cousin, VOA, which isn't adjusted based on opponent) is further explained here [2].
The simple version: DYAR means a quarterback with more total value. DVOA means a quarterback with more value per play.
Equivalent Yards (EqYds), listed in red, translate DVOA into a yards per attempt figure. This provides an easy comparison: in general, players with more Equivalent Yards (EqYds) than standard yards played better than standard stats would otherwise indicate, while players with fewer Equivalent Yards (EqYds) than standard yards played worse than standard stats would otherwise indicate. Equivalent Yards (EqYds) are not the best way to measure total value because they are more dependent on usage than DYAR.
Passes total includes sacks and aborted snaps. Both count against a quarterback's value. Fumbles count the same whether lost to the defense or retained by the offense.
